Title: Bubble flow detection
Inventor: LOYD JOHN C
IPC: B41J2/125
Filed: 1997-04-29
Abstract: A fluid flow detection method is used in a continuous ink jet printer which generates a row of parallel selectively charged drop streams from a fluid system. In the fluid flow detection method, a low airflow catcher device is provided for establishing bubble flow in an associated catcher vacuum port and catcher return line. The catcher return line contains catcher return fluid. Pressure fluctuations are monitored in the catcher return fluid to the ink tank, the ink tank having a tank vacuum. The tank vacuum is automatically lowered to a preset value, which preset value is greater than bubble flow transition. The tank vacuum is then incrementally lowered as pressure fluctuations are monitored. The tank vacuum is maintained at a constant level when the pressure fluctuations decrease below a predetermined level due to the establishment of bubble flow. Finally, the fluid flow detection method requires increasing the tank vacuum by a predetermined increment and maintaining that tank vacuum as the operating point for bubble flow for the printer .

IPC: A01G17/14
Filed: 1997-06-12
Abstract: Stakes for wire frames in wine or fruit growing, which have an approximately U-shaped cross section and hooks arranged on the legs of the U-profile. The hooks are shaped by punching and bending tongues from the steel sheet into their shape. Simple measures are proposed to prevent the tongue from being pressed into the punched hole again when the hook is impacted by operationally conditioned blows. These measures comprise laterally bending the tongue to prevent its alignment with the hole, widening the tip of the tongue so that the tongue is wider than the hole, and/or narrowing the hole.

Patent CA-2212180-A1 (CA)
Inventor: THAM ROBERT Q
IPC: A61M16/12
Filed: 1997-07-30
Abstract: A system for the delivery of nitric oxide therapy to a patient that allows interventions by a user by activating a pause mode through a user input.  A CPU in the system recognizes the activation of the pause mode and sends a signal to close a valve in order to discontinue the supply of nitric oxide to the patient.The activation of the pause mode also deactivates the normal alarm systems. A timer is activated when the system enters the pause mode and the timer allows a predetermined amount of time to pass while the pause mode is in effect. After that predetermined period of time has elapsed, the timer causes the CPU to reopen the valve to reestablish the flow of nitric oxide for the continued therapy and reestablish the alarm system.  The pause mode can be thus carried out without changing any alarm settings, established flows and the like so that the therapy is again recommenced at the same conditions as were in effect prior to the initiation of the pause mode.

IPC: G02B6/28
Filed: 1997-11-27
Abstract: An optical fibre having a small numerical aperture (NA) is optically coupled with a short birefringent crystal to provide a polarization beam splitter. This arrangement obviates s the use of a GRIN lens coupled between an input optical fibre and the birefringent crystal and provides significant cost savings by allowing a short crystal to be used.

Filed: 1996-07-31
Abstract: Des prolongements acides d'acides aminés vers des protéines de fixation multimères d'acides nucléiques (par exemple, A D N ou A R N) créent de nouvelles protéines de fixation d'acides nucléiques capables d'inhiber le fonctionnement de protéines cellulaires, ce qui permet de réguler et de moduler la croissance cellulaire. Ces protéines de fixation d'acides nucléiques sont conçues par génie génétique pour contenir une pluralité d'acides aminés acides ajoutés aux protéines, généralement en tant que prolongements du domaine de multimérisation ou de dimérisation au niveau de l'extrémité amino. Ces protéines de fixation d'acides nucléiques à prolongements acides jouent le rôle de puissants négatifs dominants, dont on a découvert qu'ils inhibent l'activation de transactivateurs endogènes, tels que AP1. L'invention concerne de nouveaux procédés de création de protéines de fixation d'ADN pouvant réaliser une hétérodimérisation spécifique et stable avec des protéines de régulation cellulaire et moduler la croissance cellulaire. Les protéines de fixation d'acides nucléiques appropriées pour des prolongements acides englobent des membres des familles de protéines de régulation de transcription, par exemple, des protéines de bZIP et de HLH, possédant des motifs caractéristiques de leucine en fermeture-éclair, ainsi que des motifs hélice-boucle-hélice, respectivement. Les prolongements N-terminaux des régions de base des protéines de fixation d'acides nucléiques sont composées d'une séquence de résidus d'acides aminés, dont tous ou quelques uns sont de nature acide, et produisent des négatifs dominants robustes des protéines natives de contrepartie dans la cellule. Le prolongement N-terminal acide crée une surface unique d'interaction protéine-protéine et permet à une multimérisation ou à une dimérisation stables de s'effectuer entre une protéine native et la protéine à prolongement acide, ce qui module, par inhibition ou par inactivation, les fonctionnements de produits de protéines cellulaires de diverses espèces, y compris des végétaux, des animaux, des micro-organismes et des virus.

The equipment suitable to carry out this method comprises autonomous locomotion means to be able to reach the open countryside, a tank to transport water or another suitable substance and a related appendage to convey it into the soil, a second tank for the compound that is to react exothermically with water and/or steam, or, in general, with the substance transported in the first tank, and means for dispensing the compound into the soil. It can also be provided with a boiler to heat or vaporize the reactant contained in the tank, as well as an agricultural tool to favor the mixing of the compound, the penetration of the reactant into the soil and the subsequent reaction thereof.

Preferably, each of the fibers (12) of the fraction penetrating the foam material (4) emerges from the outer surface (16) thereof and thereby provides a pilosity (17) thereon. The laminated product (2) is suitable for use as an insole as well as a slip-in insole in any footwear. It takes advantage of the resilient properties of the foam, the stiffness and thermoformability of the fibrous mat and the comfort provided by the pilosity covering the upper layer of foam.

Title: A method for direct sequence spreading of a data sequence (dsss)
Inventor: LINDBLAD ARNE
IPC: H04J13/00
Filed: 1996-10-25
Abstract: The present invention relates to a method for direct sequence spreading of a data sequence (d(t)) or a modulated data sequence (s(t)). The method yields better spectral properties than conventional methods for data transmission using direct sequence spread spectrum (DSSS) and is also suitable for systems where one wants to conceal the existence of transmission, so-called stealth radio. This is achieved by one or more spreading sequence generators (21) in the transmitter and the corresponding sequence generators (31) in the receiver emitting new output data at a rate which essentially exceeds the one required for obtaining in the transmitter a certain desired spread bandwidth, the spreading sequence or spreading sequences (c(t)) being caused to bandspread the data sequence (d(t)) or the modulated data sequence (s(t)), and the desired spread bandwidth being obtained by filtering in band-limiting filters (22).
